I'm trying to sync the data between parse.com account (which is production) to another parse.com (which is development). Any ideas? I have found a way to export the production into CSV, but I can't import it with the relations and pointers.
Due to import function seems not supported, you should try to duplicate your mongodb from prod to dev.
First, following the migration guide(db part) point the db by your uri. Second, duplicate the prod db to another db, and get another uri. Third, create new Parse APP with this uri.

who can help me to understand this scenario please. let say there is a client who have been using php as Backend, now he wants to merge his project from php to Spring knowing that he already has a full data and completly defined (mapping, primary key, tables), he export his data as sql (database.sql) so my question is how can we work and interact with this data in Spring Data ?
So you have the database export file(s), you create a new empty database and import those files there, configure your Spring Data to connect to the new db and stop using the Php app if you can (if you continue to use it you will have to somehow synchronize the two databases, more complicated)
Here is the official docs for Room Database. It contains the following code
val db = Room.databaseBuilder(
applicationContext,
AppDatabase::class.java, "database-name"
).build()
I was wondering what the "database-name" in the database builder does. What practical and tangible effects does it have?
Room is a Jetpack's wrapper on Sqlite DB. Sqlite holds data in single database file. So using "database-name" in Room's builder you'll get "database-name.db" file on filesystem.
In theory one app could deal with several SQLite databases. To switch between them you use different database names. If you have single database in your app its name isn't so crucial
I have completed the parse migration completely including the data and files. The clients are also pointing to the standalone parse server.
I have missed to finalize the migration in parse dashboard and now it is showing me the migrate button again. Will this create a problem when parse hosting shuts down? Do I need to migrate the data again and finalize it?
It's fine. You don't need to worry as you can try again but you will first need to clean up your target database as Parse's migration tool will only migrate data to an empty database.
I want to export and import an entire schema from Prod to Dev, but Dev has already existing tables (that are not there in Prod) which I don't want to be affected.
So, the question is during import (impdp) what happens to those existing tables?
thanks.
if you have backuped full database including create database and create tables queries in backup then there occurs error.
To solve the problem you needs to remove each line that is intented to create database and new table.
if you have dumped data only data is added to existing table with no errors. (if contains no syntax error)
if You don't need data in dev database Then login to database server and delete all tables that are in prod and then import your database file.
if You don't want to delete data in dev database Then create entirely different database import file to that database and modify your connection string.
I have a properly functioning up to date 10g database locally that I don't want to mess with. I need to do some queries on a customer's database locally which is a couple versions behind from our current software. I had exported their full db using expdp. The user is the same, and the structure is pretty much the same. What is the proper way of having both databases loaded at the same time?
If I have worded this funny, or am going about this in the wrong way, please let me know! Thanks!
Edit:
There is one main user, and another user for each component/application within the main app.
Use Import Data Pump (impdp) with the "remap schema" option to load the exported schema into another schema in your existing database:
